Electric connector with shield contact

Abstract

The invention relates to an electric connector with a shield contact. This connector comprises a sleeve with a cavity designed to receive the end of at least one cable provided with a first contact and a shielding ferule, and an outer surface. This connector also comprises a metal shield contact ring having at least one inner elastic tongue extending toward the inside of the cavity to establish an electric contact with the ferule, and at least one outer elastic tongue extending toward the outside of the outer surface to establish an electric contact with the shield of a counter-connector or a housing incorporating a counter-connector having a second contact connected to the first contact, when the connector and the counter-connector are coupled.

The invention claimed is: 
     
       1. A connector assembly, comprising:
 a connector; 
 a counter-connector; and 
 a shield wall, wherein the connector includes a first contact housed in a sleeve, made of electrically insulating material, and attached to an end of a cable equipped with a shielding sheath and a shield contact ring made of electrically conductive material, wherein the counter-connector comprises a second contact, and wherein the shield contact ring comprises an inner portion located inside the sleeve and electrically linked to the shielding sheath and an outer portion, located inside the sleeve, made in one piece with the inner portion and electrically linked to the shield wall. 
 
     
     
       2. The connector assembly as claimed in  claim 1 , wherein the connector comprises a support of electrically insulating material extending radially around and outside the sleeve and attached to the shield wall, and wherein an interface gasket is placed between the support and the shield wall, around the sleeve and the outer portion. 
     
     
       3. The connector assembly as claimed in  claim 1 , wherein a cable gasket is placed around the cable, inside the sleeve and on an other side of the first contact from the inner portion of the shield contact ring. 
     
     
       4. The connector assembly as claimed in  claim 3 , wherein the shield contact ring bears on a first section of the sleeve, and the cable gasket bears on a second section of the sleeve, distinct from the first section of the sleeve. 
     
     
       5. The connector assembly as claimed in  claim 1 , wherein the inner portion-of the shield contact ring is electrically connected to a ferrule placed around the shielding sheath. 
     
     
       6. The connector assembly as claimed in  claim 1 , wherein at least one of the inner and outer portions of the shield contact ring comprises at least one resilient tongue. 
     
     
       7. The connector assembly as claimed in  claim 1 , wherein the shield contact ring is formed by a wound metal strip section. 
     
     
       8. The connector assembly as claimed in  claim 7 , wherein the outer portion extends from one edge of the wound metal strip section and passes through a wall of the sleeve. 
     
     
       9. A connector, comprising:
 a sleeve formed of electrically insulating material, having a wall with an inner surface and an outer surface; 
 a shield contact ring made of electrically conductive material, wherein the shield contact ring comprises an inner portion, located inside the sleeve and bearing on a first section of the inner surface of the wall of the sleeve, and an outer portion, located outside the sleeve, made in one piece with the inner portion and extending the inner portion through at least one opening formed in the wall of the sleeve. 
 
     
     
       10. The connector as claimed in  claim 9 , wherein the shield contact ring is formed by a wound metal strip section, and the outer portion extends from one edge of the wound metal strip section and passes through the opening formed in the wall of the sleeve. 
     
     
       11. The connector as claimed in  claim 9 , comprising a support of electrically insulating material extending radially around and outside the sleeve, and an interface gasket placed on the support, around the sleeve and the outer portion.
